Preferably, the article is molded from polycarbonate and the process entails immersing the molded article in a dye bath that contains water, dye, a carrier and an optional surfactant. The carrier is a compound conforming toR1[-O-(CH2)n]mOR2 (i)wherein R1 and R2 independently denote H or C1-18 alkyl, benzyl, benzoyl or phenyl radical which may be substituted in the aromatic ring by alkyl and or halogen, preferably R1=butyl, R2=H, n is 2 or 3 and m is 2 to 35. The method is especially useful in the manufacture of tinted lenses.
